Be itknown that I, :GEORGE W. Poss, a

' citizen ofthe United States ofAmerica,

and resident of the city of-Cairo,'Monarchy of Egypt, have invented" a; ne ana useful Oil-Burner, of. which the following is a specification. 1' t This" invention "relates to an oil, burner, and particularly'pertains to thetypeof oil burffers in wliiclnlieavy oils are atomized and mixed with steam. Q

It is the object of this invention to provide an oil burner in whichth'e foil and steam are intimately" intermixed at the point of discharge fromthe burnerand wherein-the oil is heated-to render itfmore volatile'andsubject to atomization within the burner by the, action of the steam with out coming in direct contact with the latter.

Another object is to provide an oil burner injwhichthe oil may b e d'elivered to the burnerby gravity flow- 'and'ej'ecte'd therefrom into a -combustion chamber by steam under ];f ressure' in suchmanner as to form a broad spreadingfreadily combustible mixture ofoil and steam. i

A further object is to providei a construction in the burner gwheret a uniform delivery of the oil "andsteam is effected, and bywhich clogging ofthe burner is, obviated. Another object is to provide a burner composed of'fewpa'rts which may be'readily assembled? and separated and in which-the oil and steam" chambers; within the; burner.

easily accessible." .7 V Other obj :e'ct's will? appear hereinafter. I I

In carrying out my invention I form the 7 burner" with "an; intermediate portion or blockhaving'depressionson its upper and lower'fa'ces forming oil and steam distributing'chambers "respectively; which are covered'by top andbottom fplat'es through which the. oil and steamfarev delivered to the oliambers; the'oil land'steam being separately. discharged from their chambers and intermixed atone enaor the burner as will appear hereinafterf,

" The invention is illustrated in the accompanying drawings, in which:

, ,oIL-BURNERI Specification of Letters Patent, Patented 20, 1919. agpneanon filed July23,1917. Serial No'. 182,377.

Figure 1 is a burner. I

Fig. 2 is a view in perspective of the top Rlttfi of the burner as seen from the unders1 e. Fig. 3 is a View in perspective of the intermediate block of the burner showing its upper face.

Fig. 4 is a perspective View showing its under face.

Fig. 5 is a perspective view of the bottom plate with the spacing gasket thereon.

Fig. 6 is a view of the, burner in longitudinal section and elevation.

More specifically 7 indicates the burner block which is provided with a flared U- shaped depression on its upper face formed by a U-shaped flange 8 the inner side walls of which are outwardly divergent; the de pression opening at one end of the block. A pair of spaced diverging fins 10 extend longitudinally of the depression from a point adjacent the inner end thereof to the edge of the, block, dividing the depression perspective view of the of the block into a series of outwardlyeXpanding longitudinal channels, 11. A shallow recess 12 is formed at the inner end of the depression from which distributing grooves 13 lead along the bottom of the channels 711. The underside of the. block is formed with a marginal fian'ge'l l to provide, a recess 15; the portionof the flange extending across the endof the block constitutinga depending ledge 16. I y g The'block 7 is covered by a top plate 17 formed with an internally threaded boss 18 having an opening 19 arranged abovethe recess 12. An oil feed pipe 20 connects with the boss 18 and leads from any suitable source of supply through which oil is delivered by gravity flow to the distributing chamber in a downward direction. As a means for preventing oil discharged from the opening 19 from spreading over the underside ofthe top plate an annular channel 21 is formed in the top plate concentrio with the. opening 19 to form a lip 21 on the margin of the latter.

A bottom plate 22 covers the underside of the block and the recess 15 to form a steam chamber; a U-shaped spacing gasket 23 being interposed between the bottom plate and the flange 1 1 to form a tight joint.

This gasket in not extending across thev ledge 16 forms a narrow horizontally elongated discharge slot 24. A steam supply pipe 25 connects with an internally threadedboss 26 on the bottom plate having an opening 27 leading upwardly to the steam Y chamber beneath the opening 19 so that steam entering the steam chamber will strike the underside of the block at a point oppositethat at which the oil drops thereon.-

A series of bolts 28 pass through openings 29 in the top plate block and bottom 1 plate on which nuts 30 are screwed to bind the parts together, and formed on the top plate is a flange 31 by which the burner is attached to a suitable support.

In the operation of the invention oil is delivered by gravity How to the chamber formed by the space between the block and top plates, the oil dropping directly into the recess and being-distributed therefrom into the channels 11 by means of the grooves 13,

The oil isthus evenly distributed as it flows along and spreads over the bottom of the channels and is uniformly discharged over the end of the block from whence it passes downwardly in a thin curtain or film in front of the slot. The bottom 22 projects beyond the end of the block to form a ledge which serves to prevent oil from dripping from the burner nozzle and insures all oil delivered in front of-the slot being acted on by steam emitted from the slot.

Steam is admitted under pressure to the steam chamber beneath the block and heats the floor of the oil chamber so as to warm the oil and render it more volatile and susceptible to atomization, the steam passing through the restricted slot beneath the ledge with considerable force so as to strike the curtain of oil delivered from the oil chamber, and impel the oilhorizontally ina thor- 7 l oughly atomized and highly combustible plates'are removed, which fully exposes the spaces formed in the burner block.
